PSA: Giving promotion privilages to someone in your FC gives them all privilages

[Destinova]

IIRC you can't promote yourself higher than yourself but you can promote others higher than you.

And they cant promote to the ownership level, but they could promote to a level that is so strong that it basically does everything that is important (and effectively destroy the FC).

Say you have a another rank like Co-GM above officer, then an officer that can promote can promote himself to Co-Gm.
